Check the unmoderated posts for all the subreddits you moderate

To use any of the above links for specific subreddit you simply replace "mod" with the name of your subreddit. By combining the names of subreddits with +you can make a selection of specific subreddits.

Allow a moderator to set a spammer as "autobanned". The script will then automatically confirm removal of all of their posts in the modqueue (upon every load) and hide these entries. The sidebar will be modified to contain a list of these users, and will allow their removal from the list.

Implementing flairs can be hard and time consuming work. The this guide covers a method will that prep your sprite sheet for you, and automatically process the coordinate output into css which you can simply drop into your sub and go. Once you know what you are doing, the whole process takes less than 5 minutes for an infinite number of items of flair.

Sometimes useful to confirm if you are dealing with someone that is in it for the karma and not content quality.

GlossaryConfirm/remove ham - Used if you want to remove posts/comments that are not spam. If you use confirm/remove spam the spam filter will try to auto-remove similair posts.Shadowban - A site-wide ban on a user that the user is not notified of. This is usually the result of breaking reddit's rules. The user is unaware of the ban because their posts will still show up for them, but nobody else will see the user's activity.Distinguish - A mod has the ability to Distinguish a post, this marks a submission or comment with a green [ M ]/changes the username to green, and indicates that it has been posted in the official capacity as a moderator.

Things you might want to know
The amount of up and down votes on a submission are fuzzed, this vote fuzzing is done for anti-spam reasons. So don't be alarmed if a lot of submissions to a subreddit appear to have a few downvotes, this is normal.

users here now Is a fuzzed approximate of the users viewing the subreddit in the past 15 minutes if the amount of users is <100..

Good moderation practices

Review reported links, removing or ignoring as needed
On a periodic basis, you should review the reported links. Always be sure to leave a distinguished comment when banning a post.

Sometimes, it’s easy to tell why a link was reported: the link may be broken, the post may be completely off-topic for your subreddit, or it might break whatever special rules you have for your subreddit.If you can’t tell, then just ignore the report.If you’re a junior moderator, and you think it might be questionable, or you’re just unsure, then don’t click ‘ignore’ and discuss it with the other moderators.

Review the spam listing
The procedure here is the same as for reports. Review the posts and comments stuck in the spamfilter and take appropriate action.

Monitor submissions and comment threads, removing posts when appropriate
A useful tool to do this is by using the links listed at the top of this post. Remember to leave a distinguished comment where needed.

Ban users when necessary
This is the most extreme sanction a moderator has available for dealing with troublesome users.If a user has had their posts repeatedly banned, and if they’ve shown no inclination to follow the rules of the subreddit, then you can ban them completely from the subreddit. If you are a junior moderator, you will probably want to discuss this with other moderators before banning a user completely.Note that when you do ban a user, they will get a PM, from you, stating that they have been banned. As mod you can also train the spam filter to "shadowban" a user, if enough of his posts get flagged as spam the filter will start to remove future posts and comments, this can be useful for those users that love drama.

Respond to PMs from users
Users contact the moderators for a variety of reasons, including:

asking if their submissions have been caught in the spam filter

asking for help or guidance with a variety of things

to report inappropriate behavior by other redditors

Please be courteous and helpful when responding to users who are asking questions in good faith.If they are asking about the spam filter, the easiest thing to do is to go directly to their user page.You can see all bans and reports from there, and unban them as needed.Answer their questions if you can, and if you can’t, try to find someone who can, or have them post their question in /r/help.

Final notes

This is a collection that for me covers most aspects that you can encounter as a mod. Missing something extremely useful? Let me know and I'll see if I can put it in.
I tried to link to the original authors where possible, if I forgot to give credit please let me know.

Ok I am starting to run into the character limits of a self post.
So I'll be using this post for listing all the people that provided me with the great material that made this list possible. So in no particular order:
